Symptoms
Requests with long URLs are being rejected by Apache with the following error message:
1

Request-URI Too Large
The requested URL's length exceeds the capacity limit for this server.
Apache/2.2.3 (CentOS) Server at .... Port 443
Cause
Apache limits the allowed size of a client's HTTP request-line (e.g. <HTTP METHOD> <URL> <protocol version>) and the HTTP request header field size. The default values may need to be increased if the request URL is large.
Resolution
Increase the Apache limits for limit request line and limit request field size.
